I have a table with 3492 rows. I want to update a boolean column from

Is there a way to access a file with those condition values? If not, should
I create a temporary table with one column containing those values, or do I
write a psql script with 295 lines, one for each row to be updated?
A plain UPDATE might work.
UPDATE to_be_updated a
SET bool_col = true
FROM other_table b
AND b.field3 = mumble;
(You can join them, right?)
